Order your own 'Infidelity Test Kit'~

Wow..I just noticed this ad above someone else's discussion..It is an actual test kit that is sent to you that can aide you in the detection of infidelity of a spouse or significant other (it is probably with this discussion also, given the tags of this discussion) I have never heard of such a thing until now, and with all the DNA testing that is done now, it is no surpirse that it can be done -just the fact that you can order a 'kit' and do your own detective work yourself~! A polygraph for faithfulness..Another + for technology!
Is there anyone out there who has actually used this~?
Any comments~?

It is a bit funny..I realized AFTER i posted the discussion and after looking at this site more clearly, that you do not receive a 'kit'..You send in the samples to this place, and wait for word from them~
Thank you ;)
